Events [ edit ]

Byzantine?Sassanid War : Emperor Heraclius invades Armenia , leaving his son Constantine (age 11) and co-regent Bonus to defend Constantinople against the Persians still at Chalcedon (modern Turkey ). He sails with 5,000 reinforcements to join the Byzantine army at Trapezus . Raising additional forces in Pontus , Heraclius strikes through the mountains of Armenia and the northern sub- Caucasian principalities. He plunders Media ( Azerbaijan ), and avoids the Persian armies who attempt to trap him. ^[1]

King Clothar II gives Austrasia to his son Dagobert I , age 20, effectively granting the kingdom semi- autonomy in repayment for the support of its nobles , most notably Pepin of Landen ( Mayor of the Palace ), and in recognition of calls from the Austrasians for a king of their own. Arnulf , bishop of Metz , becomes advisor to Dagobert.
Samo , reputedly a Frankish merchant, is elected king of the Slavs in Moravia , Slovakia and Lower Austria . A string of victories over the Avars proves his utilitas (usefulness) to his subjects, and he secures the throne to establish his own kingdom , which stretches from the upper Elbe to the Danube . ^[2]
